Mortgaging

No doubt, the Prophet mortgaged his armor for barley grams. Once I
took barley bread with some dissolved fat on it to the Prophet and I
heard him saying, "The household of Muhammad did not possess except a
Sa (of food grain, barley, etc.) for both the morning and the evening
meals although they were nine houses."

Allah's Apostle said, "Who would kill Ka'b bin Al-Ashraf as he has
harmed Allah and His Apostle ?" Muhammad bin Maslama (got up and)
said, "I will kill him." So, Muhammad bin Maslama went to Ka'b and
said, "I want a loan of one or two Wasqs of food grains." Ka'b said,
"Mortgage your women to me." Muhammad bin Maslama said, "How can we
mortgage our women, and you are the most handsome among the Arabs?" He
said, "Then mortgage your sons to me." Muhammad said, "How can we
mortgage our sons, as the people will abuse them for being mortgaged
for one or two Wasqs of food grains? It is shameful for us. But we
will mortgage our arms to you." So, Muhammad bin Maslama promised him
that he would come to him next time. They (Muhammad bin Maslama and
his companions came to him as promised and murdered him. Then they
went to the Prophet and told him about it.

Allah's Apostle said, "The mortgaged animal can be used for riding as
long as it is fed and the milk of the milch animal can be drunk
according to what one spend on it. The one who rides the animal or
drinks its milk should provide the expenditures."

Abdullah (bin Mas'ud) said, "Whoever took a false oath in order to
grab somebody's property will meet Allah while Allah will be angry
with him." Allah revealed the following verse to confirm
that:--"Verily! Those who purchase a small gain at the cost of Allah's
covenant And their oaths...a painful torment." (3.77)

Al-Ash'ath bin Qais came to us and asked as to what Abu Abdur-Rehman
(i.e. Ibn Mas'ud) was telling you." We related the story to him. On
that he said, "He has told the truth. This verse was revealed about
me. I had some dispute with another man regarding a well and we took
the case before Allah's Apostle. Allah's Apostle said (to me),
"Produce two witnesses (to support your claim); otherwise the
defendant has the right to take an oath (to refute your claim).' I
said, 'The defendant would not mind to take a false oath." Allah's
Apostle then said, 'Whoever took a false oath in order to grab someone
else's property will meet Allah, Allah will be angry with him.' Allah
then revealed what Confirmed it." Al-Ash'ath then recited the
following Verse:--"Verily! Those who purchase a small gain at the cost
of Allah's covenant, And their oaths . . . (to) . . . they shall have
a painful torment!' (3.77) (See Hadith No. 546)
